Indeed.  You will also need the sending unit and the wiring, too.

The voltage stabilizer, whether store bought or home grown, needs a good 
ground.  Grounding it to the back of the gauge (as is typically done by the 
factory) can, in time, lead to the problems you are seeing.  Sometimes the bad 
ground is within the stabilizer itself.  Not so likely in home brew units 
with are most likely soldered but the crimp connection on the Lucas units can 
corrode and cause problems.
